This paper develops an equilibrium asset and option pricing model in a production economy under jump diffusion. The model provides analytical formulas for an equity premium and a more general pricing kernel that links the physical and risk‐neutral densities. The model explains the two empirical phenomena of the negative variance risk premium and implied volatility smirk if market crashes are expected. Model estimation with the S&P 500 index from 1985 to 2005 shows that jump size is indeed negative and the risk aversion coefficient has a reasonable value when taking the jump into account.  相似文献

We develop a model of illiquidity transmission from spot to futures markets that formalizes the derivative hedge theory of Cho and Engle (1999). The model shows that spot market illiquidity does not translate one to one to the futures market but, rather, interacts with price risk, liquidity risk, and the risk aversion of the market maker. The model's predictions are tested empirically with data from the stock market and markets for single-stock futures and index futures. The results support our model and show that the derivative hedge theory provides an explanation for the liquidity link between spot and futures markets.  相似文献

Using nonparametric methodology, I find that speculators are successful in taking profitable positions in energy futures markets, although the magnitude of this effect is lower than that found previously for agricultural markets. A plausible explanation for this difference is that price forecasting is more difficult for energy commodities. Moreover, I find that the energy speculators’ returns are due to the existence of the risk premiums rather than to speculators’ forecasting abilities. Futures risk premium is highly time-variant; notably, energy investors’ profits have been very limited in the GFC and post-GFC period, which coincided with the financialization of commodity markets.  相似文献

China is a leading participant in the world cotton market. China’s distinctive regulatory structure and procedures and business environment provide an opportunity to explore some unique market dynamics. This study investigates the interrelationship among the spot, futures, and forward cotton markets in China over a period of a major policy change: A temporary State reserve program for cotton that was established in 2011 and ended in 2014. This government intervention significantly distorted the way farmers, manufacturers, and speculators interacted and was not sustainable. Overall, our results support futures market’s dominant role in the price discovery process.  相似文献

This paper develops a novel, general derivative pricing model which introduces a liquidity risk factor. The model variants we outline offer a sufficient degree of flexibility so as to enable the valuation of various types of derivative classes including futures, American options, and mortgage backed security options, whereas existing derivative models can only price liquidity risk in European derivatives. We validate the model with oil and gold futures data and compare it to a classical benchmark model void of any liquidity risk. We find that our model is significantly more accurate than the classical model for pricing both oil and gold contracts.  相似文献

The Capital Asset Pricing Model (CAPM), and the Fama-French and Carhart models have been widely applied in the developed and most emerging markets; however, there is scant evidence of the viability of the models on the African Frontier Stock Markets (AFSMs). This study examines the viability of the models for a sample that pools securities across nine AFSMs, and whether or not the risk factors of these models command risk premium on the AFSMs. The paper provides evidence of the existence of the size, value and momentum effects on the AFSMs. In addition, the models only partly capture the returns to size and book-to-market sorted portfolios on the AFSMs. Also, the risk factors of these models generally, command marginally significant premium on the AFSMs. Caution should in general be exercised when applying these models on the AFSMs.  相似文献

I develop and test a model to study the interaction between the commodity and stock markets. This study attempts to clarify the debate about the effect of financialization on commodity markets. Theoretically, the futures risk premium is determined by hedging pressure, stock market returns, and the commodity–equity correlation. Empirically, the effect of the stock market on the energy market became significantly greater for the futures risk premium in the period following the 2008 crisis. Furthermore, hedging pressure is a strong explanatory variable for the futures risk premium in various circumstances.  相似文献

This paper examines the weekend effect in futures markets and presents rational and behavioral reasons for its existence. Specifically, we document a weekend effect (Friday's return minus the following Monday's return) in futures markets. The weekend effect occurs partly because of asymmetric risk between long and short positions around weekends; the weekend effect increases when short positions are relatively more risky. In addition, we find that both lagged and contemporaneous changes in investor sentiment are related to the weekend effect. These results are consistent with the investor sentiment literature that finds that mood improves on Fridays but deteriorates on Mondays.  相似文献

CHOQUET INSURANCE PRICING: A CAVEAT   总被引:1,自引:0,他引:1  
We show that, if prices in a market are Choquet expectations, the existence of one frictionless asset may force the whole market to be frictionless. Any risky asset will cause this collapse if prices depend only on the distribution with respect to a given nonatomic probability measure; the frictionless asset has to be fully revealing if such dependence is not assumed. Similar considerations apply to law-invariant coherent risk measures.  相似文献

This paper augments the theoretical foundations of organized commodity futures markets and uncovers singular facts about arbitrage and the role of information. Using the term "credit agency" to embrace organized futures markets such as the Chicago Board of Trade as well as independent brokerage houses, we extend the extant theory of temporary equilibrium for an economy with a single credit agency to economies with many credit agencies. In the process, we find that arbitrage with no risk of bankruptcy and with perfect interagency trade information can be incompatible with equilibrium (exact or approximate). On the other hand, the usual regularity assumptions are sufficient for the existence of at least an approximate equilibrium, provided that interagency trade information is imperfect (or risky). However, such imperfect information limits arbitrage so different agencies can have different prices.  相似文献

对美国大豆期货市场与现货市场价格传导关系的实证分析表明,美国大豆期货市场与现货市场相关性较强,期货市场与现货市场之间存在显著的长期均衡关系;期货市场和现货市场存在误差校正机制,当偏离两者的长期均衡关系时,重新回到原有均衡关系的调整速度较快;期货市场与现货市场相互引导,但现货市场的引导作用大于期货市场.文章提出,发现价格和套期保值是期货市场最基本的功能,这些功能的发挥与现货市场的发展密切相关.期货市场的产生与发展并不是对现货市场的替代,而且在完善的市场体系中,现货市场对期货市场具有较强的引导作用,现货市场发展的程度是影响期货市场功能发挥程度的关键因素.不断改善现货市场环境,加强现货市场建设,是促进期货市场快速发展的现实选择.  相似文献

The risk premium associated with large upside jumps in oil market is a significant driver of the cross-section of stock returns from 1986 to 2014. In contrast to previous research, variance risk is priced only when we do not control for jumps. Upward jumps are priced in tight supply-demand conditions but not in more abundant supply periods. There is some evidence that downward jumps are priced in abundant supply conditions but not in tight conditions. Innovations in risk neutral jumps have predictive power for important economic indicators, including notably consumption growth. This helps explain the pricing of jump risks.  相似文献

This paper studies the forecasting of volatility index (VIX) and the pricing of its futures by a generalized affine realized volatility model proposed by Christoffersen et al. This model is a weighted average of a GARCH and a pure realized variance (RV) model that incorporates each volatility component into the new dynamics. We rewrite the VIX in terms of both volatility components and then derive closed‐form formulas for the VIX forecasting and its futures pricing. Our empirical studies find that a unification of the GARCH and the RV in the modeling substantially improves the forecasting of this index and the pricing of its futures.  相似文献
